Otherwise, the new element that added may change the order of the min-max heap, So we need to adjust the heap with pushUp: private void pushUp(List<T>h,int i) { if (i != 1) { if (isEvenLevel(i)) { if (h.get(i - 1).compareTo(h.get(getParentIndex(i) - 1)) < 0) {...
There are cases where we prefer to use recursive functions such as sort (Merge Sort) or tree operations (heapify up / heapify down). However, if the recursive function goes too deep in some environments, such as in Visual C++ code, an unwanted result might occur such as a stack-overflow....

Let’s first look at building a min-max heap from an existing array. Here we use Floyd’s algorithm with some adaption like theHeapify algorithm: publicList<T>create(){for(inti=Math.floorDiv(array.size(),2); i >=1; i--) { pushDown(array, i); }returnarray; }Copy Let’s see wh...
